Kent RO — Fraud Service Team

I filed a service request for under warranty product for low water flow. The service person came and said install an exterior candle filter. I refused as it was not of kent. The technician intentionally damaged sediment filter and now that water flow stopped completely they are misbehaving and abusing ladies. Even after complaining on given contact no. Their response is jo karna hai karlo.

If this is service for under warranty I wonder what will be after warranty is over.
